In 1908, what fraction of U.S. NOx emissions was contributed by highway transportation? By electric utilities? What were these fractions m 2008?
Calculate the emissions of NOx from all the vehicles in Orange County, Florida, in 2008. The fleet-average NOx emission factor for 2008 was 1.645 g/mi and the total vehicle miles traveled (VMT) in that year were 13.53 billion miles,
Calculate the total mass of CO2 in the atmosphere. State all assumptions. Compare this to the actual of ~3.6 ×1012 tonnes. At our current rate of emissions, how long would it take to emit a quantity equal to the present mass of CO2 in the atmosphere
